What else can I help you with?
What is the period of the voltage waveform out of a wall outlet?
60 seconds
What is a TVSS in Electrical Engineering?
A TVSS is a transient Voltage Suppression System. It activates in times of a high voltage condition. The high voltage condition could be caused by many things such as a lightning strike or a transformer failure.
Why does the speed of the DC series motor rise to a run away condition if full voltage is applied while there is no load?
At no load, the speed of a series motor rises to a run-away condition if the full voltage is applied because the applied voltage appears directly at the terminals of the motor and drives it to a run-away condition since speed is proportional to the voltage.
Can you connect an AC source in series to DC source - then what happens to the current under a steady state condition?
With an AC and a DC voltage source in series, the DC voltage can be added to the RMS value of the AC voltage to give the effective voltage.
What condition the relays should be use in power voltage?
Inorder to achieve the impedance maching ....

Why voltage in transformer suddenly increases and then decreases suddenly?
In perfect condition, the voltage variations does not occur.. Due to failure causes, voltage variations will arise
How would you fix a starting problem in an opel astra g 2001 model?
It takes a lot of voltage to turn a starter, even if everything else works. Typically between 9-11V. First get a cheap voltage tester and check batt voltage when off. If ok, check condition of cable and at end of cable. Start there
Which condition refers to a sudden increase in voltage?
That would be 'spiking'
What is the condition when voltage drop occur when motor running?
its lose
What mechanism should be adopted to keep terminal voltage constant in varying loading condition in an alternator?
Voltage Regulator
How a zener diode is used in voltage regulator under both varying input and varying load condition?
In the varying input condition, the zener diode is used in such a that any variation in the input voltage,should not in any affect the load (that is the arrangement supplies just the voltage needed by the load no matter how high or low the supply voltage might go). In the varying load condition, the zener diode is connected in such a way that any change in the load voltage should not affect the input voltage.
Why is the measured voltage of a battery not the same as the stated voltage?
The measured voltage of a battery may not match the stated voltage due to internal resistance, temperature, or the age and condition of the battery. These factors can lead to voltage drops when the battery is in use.
Is it the value of input voltage equal the value of output voltage?
No. There are several factors that may affect the output voltage. For instance: Resistors, Transformer, Voltage regulators and others that can control the output voltage to a certain level.
How do you comfirm thyristor condition?
A thyristor if conducting will have a very small voltage drop across if not then the rail voltage will be evident across the device
